Preferably, described matrix radial extension forms described a plurality of radiating fin.
Preferably, described free end arc bending.
Preferably, the vertical described a plurality of radiating fins in described second air port.
Preferably, described first air port is the air inlet of described radiator fan, and described second air port is the air outlet of described radiator fan.
Preferably, described first air port is the air outlet of described radiator fan, and described second air port is the air inlet of described radiator fan.
Preferably, parallel described second air port, described first air port.
Preferably, the matrix of described radiator is cylindrical.
Preferably, described radiator fan comprises a locking part, and described locking part is provided with a through hole, and described radiator is provided with an installing hole, and a screw is fixed together described radiator fan and described radiator by described through hole and described installing hole.
Preferably, described radiator comprises the fixture of described radiator on a circuit board that be used to lock.
Relative prior art, the free end overbending direction of the radiating fin of the radiator of the utility model heat abstractor and the direction of rotation of radiator fan, because air-flow is subjected to the ordering about of radiating fin of described radiator in flow process, cause the intermolecular disturbance of air-flow strong, thereby improved radiating efficiency.

Embodiment
See also Fig. 1 and Fig. 2, the heat abstractor of the utility model preferred embodiment comprises a radiator 30 and a radiator fan 50.
Described radiator 30 comprise one be used to contact the heater element matrix 31 of (figure does not show), a plurality of from described matrix 31 to around the radiating fin 32 that forms of radial extension and four from described matrix 31 to around the fixed part 33 that extends, described matrix 31 is cylindrical, described matrix 31 definition one central shaft.Each fixed part 33 is between the two adjacent radiating fins 32, each fixed part 33 comprises one first installation portion 331 and one second installation portion 332, described first installation portion 331 comprises that one is used for fixing the fixture 3311 of described radiator 30 on a circuit board (figure does not show), and described second installation portion 332 is provided with an installing hole 3321.Each radiating fin 32 comprises a free end 322, and described free end 322 is provided with a gap 34 around the central shaft arc bending along clockwise direction of described matrix 31 between per two radiating fins 32.
Described radiator fan 50 comprises second air port 52 in one first air port 51 and parallel described first air port 51, in the present embodiment, described first air port 51 is as the air inlet of described radiator fan 50, described second air port 52 is as the air outlet of described radiator fan 50, and described radiator fan 50 rotates counterclockwise.Described radiator fan 50 is respectively established a locking part 522 in described second air port 52 4 sides, and each locking part 522 is provided with the through hole 523 of a corresponding described installing hole 3321.
See also Fig. 1 to Fig. 3, during assembling, second installation portion 332 of the locking part 522 corresponding described radiators 30 of described radiator fan 50 is made the installing hole 3321 of through hole 523 corresponding described second installation portions 332 of described radiator fan 50.Four screws 60 are locked the through hole 523 of described radiator fan 50 and the installing hole 3321 of described radiator 30 respectively, and described radiator fan 50 is fixed on the described radiator 30, thereby described heat abstractor assembling finishes, at this moment, second air port 52 of the radiating fin 32 vertical described radiator fans 50 of described radiator 30.
When described radiator fan 50 rotates counterclockwise around the central shaft edge of described matrix 31, the distinguished and admirable gap 34 that flows into described radiator 30 from top to bottom, because described radiator fan 50 rotates counterclockwise around the central shaft of described matrix 31, thereby drive the distinguished and admirable described radiator 30 that blows to counterclockwise downwards, and the free end 322 of described radiating fin 32 bends along clockwise direction around the central shaft of described matrix 31, because air-flow is subjected to ordering about of described radiator 30 shapes in flow process, cause the intermolecular disturbance of air-flow strong, thereby improved radiating efficiency.
